' 'WELDEDRAIL-BON'D AND FISH-PLATE.

To all whom 'it may concern.' ,i

Be it known that'I, JESSE. M. YOUN'r, a citizen ofthe United States,residingv in the city and county of San Francisco and State ofCalifornia, have invented new and. useful Improvements in WeldedRail-Bonds and Fish-Plates, of which the following is a specification.

This invention relates to rail bonds of thev type shown and described inmy Patent No.

1,037,707, dated September 3, 1912, and has for its object to improveandsimplifythe employed in the bond in such a Way as to make possible.their electriewelding without danger of injuring or weakening the railstructure to which they`` are applied.

lVhere fish plates are l,applied to opposite sides of joined `rails andelectrica'lly'welded thereto the-seams or joints will fall directlyopposite each other` in alinernent and there is danger of weakeningthe-rail structure from the concentration of heat.' In my presentinvention I"ove'rc ome this -objection by providing opposed fish platesof varying heights so that their uppe'r seamswill-not be in, alinement,and overlap them longitudinally so that their end seams hre'staggeredOne form which my inventionA may 'assume is exemplified in vthefollowing description and illustrated in twelaccompanyingdra'wings, inwhielwlmiil Figure lshows a side elevation of joined rails embodying myinvention. Fig. Qshows a. vertical, crosssectional View ofthe same.

Referring inA .detail to the drawings, joined rails l() are shown.Applied to each, tone side, is a lishl plate 11 of comparatively-largeheight and-having ends 12`op.

-positely beveled or slanted in a direction l TheV beveled ends 12 arecut Aunder at their lower ends 13 to eliminate the extremely acute an`gle at the point, leaving in steada downwardly and inwardly inclinedsurface 14. On the'side of the rails opposite the fish plate 11 is asimilar plate 15 of the same Shape as the plate 11 but of a smallerheight.

facilitate the application of the welding ma- A terial, the fusion ofwhich'is carried on electrically to weld the plates to the rails'throughout their perimeters.

It is of great import-ance in electric Welding of rail joints to. avoidtheconcentration' of the intense heat applied to the seams, for it hasbeen found in actual practice that welds or seams at opposite'sidesoftheV comparatively thin web portion '1.8 of the rails, when inalinement, will permanently weaken the rail structure. A similar injurywill result to the rails 'wherethe'sea-ms atene side overlap for-anyappreciable length, and

to eliminate this danger I have cut away the point 13 from the endsofeach {ish plate. By soundercutting the pointed ends of the plates thedownwardly and inwardly projeeting line 14 is not exposed for weldingand hence joining of the base line and the beveled end line at thepoints 1 3 is avoided.`

Having thus described my invention, what I claim and desire to secure byLetters Patent is 1. A railpjoint comprising abutting railends, andopposed Iish plates therefor: adapted to be welded to the rails at theirperimeters, said opposed plates being arranged with their top and endseamsqout of alinement.

2. Api-ail joint comprising abutting rail i vends, and opposed fishplates therefor adapted Ato be welded at their perimeters` one of saidplates' being of greater height than v,the

other andthe two beingoverlapped at their ends 3. A rail jointcomprising abuttingr rail ends and opposed fish plates therefor" adapt--ed to be welded thereto at their, perimeter-s,

said plates having acute angular ends with ltheir apices cut away toprevent coincidence of the adjacent side and end seams.

4. A Awelded rail joint comprising abutting rails and opposed fishplates, the plate 'on one side arranged with respect to its companion sothat the welding edges of the two plates are out of register.

In testimony whereof I have hereunto set' my hand in the ing Witnesses.
